[44net] Linux Gateway Question.

Hello, I'm setting up a gateway on a linux server, I have added NAT and firewall rules to send protocol 4 over to my server at 10.0.2.1. Here's some output from tcpdump. Does this look right to you? Under it I have the output from ampr-ripd, showing nothing coming in. 0.0.0.0.5678 > 255.255.255.255.5678: UDP, length 102 15:41:24.153222 IP (tos 0x50, ttl 242, id 15047, offset 0, flags [none], proto IPIP (4), length 174) ip72-192-148-49.sd.sd.cox.net > 10.0.2.1: IP (tos 0x0, ttl 64, id 0, offset 0, flags [none], proto UDP (17), length 154) 0.0.0.0.5678 > 255.255.255.255.5678: UDP, length 126 15:41:35.790028 IP (tos 0x50, ttl 232, id 5104, offset 0, flags [none], proto IPIP (4), length 166) dhcp-91-241-24-251.zc.net.pl > 10.0.2.1: IP (tos 0x0, ttl 64, id 0, offset 0, flags [none], proto UDP (17), length 146) 0.0.0.0.5678 > 255.255.255.255.5678: UDP, length 118 15:41:40.735505 IP (tos 0x50, ttl 233, id 5482, offset 0, flags [none], proto IPIP (4), length 150) 89-67-160-225.dynamic.chello.pl > 10.0.2.1: IP (tos 0x0, ttl 64, id 0, offset 0, flags [none], proto UDP (17), length 130) 0.0.0.0.5678 > 255.255.255.255.5678: UDP, length 102 15:42:24.169078 IP (tos 0x50, ttl 242, id 15303, offset 0, flags [none], proto IPIP (4), length 174) ip72-192-148-49.sd.sd.cox.net > 10.0.2.1: IP (tos 0x0, ttl 64, id 0, offset 0, flags [none], proto UDP (17), length 154) 0.0.0.0.5678 > 255.255.255.255.5678: UDP, length 126 15:42:35.827618 IP (tos 0x50, ttl 232, id 5105, offset 0, flags [none], proto IPIP (4), length 166) dhcp-91-241-24-251.zc.net.pl > 10.0.2.1: IP (tos 0x0, ttl 64, id 0, offset 0, flags [none], proto UDP (17), length 146) 0.0.0.0.5678 > 255.255.255.255.5678: UDP, length 118 root@rigel:~/ampr-ripd-2.4# ./ampr-ripd -d -i tunl0 Using gateway 10.0.0.1 for direct 44net endpoints via interface enp2s0.
